Can a person be Christian, and perform magick? I wonder. I quite found myself in Christianity as religion, but since I researched about magick before that, I think it's not bad, at all, if used the right way. :/

that's right! And magick is not a religion it's an art... And faith on it is faith on every religion and respect to the powers of nature or the paranormals... So really if magick is a religion is the embodient of faith in the world and respect to every religion
